Abstract In 2016, air pollutant emissions in the Republic of Korea were 795,044 metric tons (hereafter tons) CO, 1,248,309 NO x , 358,951 SO 611,539 TSP, 233,085 PM 10 100,247 2.5 16,401 BC, 1,024,029 VOCs, and 301,301 NH 3 . Including energy production, thirteen emission sources, which comprise national inventory, classified by their characteristics into five sectors (Energy, Industry, Road, Non-road, Everyday Activities Other Emission Sources) to analyze relative contributions emissions....

Various shipping emissions controls have recently been implemented at both local and national scales. However, it is difficult to track the effect of these on PM2.5 levels, owing non-linear relationship that exists between changes in precursor PM components. Positive Matrix Factorisation (PMF) identifies a switch cleaner fuels since January 2020 results considerable reductions shipping-source-related PM2.5, especially sulphate aerosols metals (V Ni), not only port site but also an urban...

Objectives : Volatile organic compounds discharged from industrial complexes need to be managed. They make PM, O3 etc NOx and photochemical reaction in the atmosphere become a major source of odor.Methods The environmental impacts around Sasang area Shinpyeong-Jangrim general complex were investigated by SIFT-MS, which can continuously real-time measure air pollutants such as volatile compounds. A map pollution was drawn up impact substances identified.Results Discussion Benzene all within...

We investigated the distribution of hazardous heavy metals (As, Cr6+, Ni, Cd, Pb, and Mn) estimated health risk related to in fine dust (PM-10 PM-2.5) Sasang industrial complex, Busan, Korea. The concentration complex was 1.2 times higher than a residential area, while harmful showed difference at least 1.3 (Cd) up 6.5 (Ni). carcinogenic increased significantly compared area spring (March May) winter (December February) months. A assessment performed using Monte-Carlo simulations containing...
